Whats wrong with my plants?

White Widow and Blueberry F23 days..
FFOF Soil
3 Gal Smartpots
I water them with 6.0-6.5 PH
CalMag 5ml
I use FF Trio. I currently water them every 2 days and I'll switch from just water->nutes->water.
Anyone know why this is happening to them? Rust on my white widow and looks like nuteburn on my Blueberry..

Without a picture of the whole plant to go on my first thought is a pH of 6 is too low. Keep your pH at 6.5, things should get better. And cut back or stop the Cal Mag for a while too. What's your runoff pH and PPM?

Don't even bother adjusting pH in soil. What strength are you feeding?

That's terrible advice to give Noobs. And its not correct. My pH out of the faucet is 8.9, if I put that in my plants the plants are going to die. Ever hear of pH lockout?

So going by what you say: Today I put in straight tap water at 8.9.

Tomorrow I add my newts and pH comes down to 5.8, you think that's what the plants want, bouncing pH around like that?

..that's terrible advice to give to nubes in particular who might not know better

How many people have water at that pH? Have a meter? Measure the EC or PPM of each feeding? If not why not?

OP ask for a,water quality report or look it up on line. Buy litmus paper. If the pH is near 7 forget treating pH in soil.

Wow ive never checked my runoff PH and PPM ... I'll do it tomorrow. Here are more pics though..

Plant nutrients leach out of soils with a pH below 5.0 much more rapidly than from soils with values between 5.0 and 7.5. Plant nutrients are generally most available to plants in the pH range 5.5 to 6.5. Aluminum may become toxic to plant growth in certain soils with a pH below 5.0.

Check your soil. Not your water. Kits available at Lowe's or most garden centers. Before you try to adjust by adjusting water pH .

I suspect a lot more people have higher pH than a pH that comes out at 6.5 - 7

Most people in and around cities, for example, where they raise the pH to stop the acidifying effects on the water system

.. I've seen you give a lot of good advice, but I've also seen you say this before and feel you should consider that before telling people just to dump any old water into their grow

I limit it to soil. Soil buffers however it's goijng to buffer. Indoors or out. Have you ever done a guerilla grow? I have a lot. No pH bullshit. Not in my garden either. Cannabis survived many millenia probably because man didn't help. pH can present a problem but so rare in quality soils. Just my two cents worth.

Agreed.

Most long time soil growers don't PH. Go to your local park or gardens and see all those exotic plants....all in the same soil as the natives.

Most bagged soil contains Lime and buffers a fair bit so it can be used for a range of plants.

I'm no soil expert but I know I had similar looking leaves and I used some wood ashes and some epsom salts and held off on nutes for a few days and they turned around

I've looked into it and many cities are kicking up the ph to protect old pipes; and you should get a water report or just test your tap water. But getting a ph of 8.9 out of the tap is extreme for a large water system. In smaller towns or in rural areas I'm sure it can get that high but people will start noticing a bitter taste in that range.
I grow in soil and I just don't worry too much about ph. Bad ph in soil is not a cause of problems, it's a symptom of something else, but everyone is quick to start adding stuff instead of fixing their real problems (over watering, too little/many nutes, bad soil mix, ect.).

Do you allow the pots to dry out? How do you check if they need water? How much run off? A good rinsing of your soil might be needed to remove salts.
Might want to start lighting up on nutes as you go further into flowering.

Looks like some nute burn for sure. Also looks like some fungus gnat damage. Particularly the brown circular spots. The fungus gnats themselves wont do any damage (besides sticking to buds) but the larvae will munch on roots. Also i would do a good flush on your soil and then think long and hard about going organic.

Also grab a 60x handheld microscope and check for bugs/eggs under the leaves.

They look like they need more potassium, is there enough K in the nutes you are using? You need to start extra K just before flowering next time.

I use tap water every year on my outdoor plants. Dont even have a ph water meter. I never have issues with my plants because I leave them alone and let them grow.

I have never however watered my plants every two days. I'm of the opinion marijuana grows best on the dry side. My ladies get full sun, 85-90 temps and I water very modestly every 5-7 days.

Over watering and too many nutrients cause 90% of all problems I believe.

It's a learning process. Your write up and pictures are common.
You are likely watering to often creating a low soil PH causing nutrients to be locked out.
You probably over fertilized also.

Do you have a ppm or E/C meter?
You need to know the ppms of your water.

I don't know the PPMS of my water. I will order a meter tomorrow. I've just been PHing out of the tap and its been at (8.9) and then add nutrients and measure with PH and use Up and down to get to 6.0-6.5.. At first I was doing Fox Farm Big Bloom 1 Table spoon per gallon and then 2 teaspoon of Tiger Bloom. I watered by picking up my plants to see if its really light and water. By then I saw that every 2 days it got dry so I watered it... and just been sticking to that. Am I really watering too much? The soil is pretty dry by day 2.
